// Test that typelib_typedescription_register as called from typelib_typedescription_complete
// returns a correct typelib_TypeDescription and keeps pointers from the original
// typelib_TypeDescription intact (see tdf#115399 "Data race in typelib_typedescription_register").
// This code uses sufficiently "obscure" types in typelib_static_*_type_init to make it unlikely
// that they are already instantiated and registered with the type description manager, which might
// cause inconsistencies.
